I have 2 of the 6-24x56ir Zeiss and compared to the couple of NF that i have seen the Zeiss stand head and shoulders above the NF. The picture is right there in the rear lense if you know what i mean rather than looking like its part the way down the tube!

When lamping i quite often use 14x mag an have even wound it up to 20x without any probs what so ever! Just simply stunning! When funds allow i shall get another!
